OPERATING DEVICE FOR C)ALGULATING-MACZ-HNES:

Specification of Letters Patent.

Patented Nov. 24, 1903.

Application filed lilarchB, 1905. Serial No. 29,06.

To all whom it may concern:

lie it known that l, \VILLIAM H. PIKE, Jr, a citizen of the United States, residing at Orange, Essex county, State of New Jersey, have invented :ertain new'and useful linprovcments in Operating Devices for Calculating-Machines. of which the following is a specification.

The present invention is applicable to machines of any character in which an operating shaftis moved by rocking a hand lever or handle. l

it is especially adapted for use in connection with calculating. machines, although available for use in other machines, and is designed to insure a regular action of the working shaft however abrupt and irregular may be the movement imparted to the handie. and whatever may be the differences in its speed of movement.

A further object of the invention is to provide means whereby when the invention is applied to calculating machines having a special key or operating device. such as a total key, which should be fully operated before the hand lever or handle is moved, it will be impossible to move the hand lever during the operation of such special key or to move the latter during a movement of the operating handle.

As before stated. the invention is particularly applicable for use in connection with calculating machines. although many of its features are not limited to such use; and therefore in the accompanying drawings it is illustrated as applied to a machine such as that disclosed in U. S. patent to Pike No. 7551592. granted June 28, 190%.

in the accompanying drawings,.l igure 1 is a side elevation of an adding machine having the present invention applied thereto. a portion of the casing of the machine. being ren'ioved; Fig. 2 is an elevation of a partof the machine. viewed from the opposite side from that shown in Fig. l. the parts being on an enlarged scale; Fig. 3 is a plan of the parts shown in Fig. 2; Fig. t is a sectional view of the parts shown in Figs. '2 and P). the hand lever or handle and parts connected therewith being in a different. position from that illustrated in the other figures; Fig. 5 is a detail view: Fig. 6 a: skeleton or diagrannnatic view showing parts of the invention in two positions.

Referring to the drawings, 1 designates the working shaft of the adding machine in connection with which the present invention. is illustrated, which shaft is mounted in suitable bearings in the frame of the machine and connected with a counter shaft 2 in such manner that said shafts will always move together. l. and t3 designate respectively the numeral keys, the sub-total key and the total key of the adding machine, the

construction and function of which are fully set forth in the aforesaid patent No. 763,69. and therefore do not require particular description at this time.

The operating handle 7, which may be of any suitable form, is detachably secured to one end of a shaft 8 suit-ably mounted in hearings in the main frame 9 and a bracket 10 secured to one side of the main frame. As shown, the shaft 8 is arranged in line with the working shaft 1 of the machine.

The counter-shaftis mounted in suitable bearings on the main frame and said bracket 10. and to said shaft between its bearing in said bracket and the main frame is secured an arm consisting of two parallel plates 11 connected by suitable fastening means. A similarly formed arm. comprising two plates 12. is secured on the shaft 8:- and to said arms 11. 12, are, respectively, connected plates 13. 14-. to which are secured the ends of a coiled spring 15. Said spring is arranged between a pair of bars 1G, 17, each having one end secured rigidly to the members of the arm 12 on the handle shaft 8 and having near their otherends slots 18 through which extend pins projecting laterally from the arm 11 on the counter-shaft. 2.

T he working shaft, 1, is provided with an arm 19. which is connected with an arm 20 projecting from the. countershaft 2 by means of a link 21. the ends of which are pivoted to said arms 19, 20. respectively. The arms 19, 20. are preferably so related to each other and the shafts by which they are carried that when the parts are in normal position and the operating lever or handle? is elevated, as shown in Figs. 1, and 3, the pivotal connection 22 between the link 21 and arm 20 will lie substantially in a straight line connecting the axis of the shaft 2 with the point of connection. of said link 21 with the arm 19 on the working shaft. That is the arms 19, 20 and interir n between the workingshaft 1 and. conncompleted.

i plates.

tersha ft by means of which said shafts are caused to always move together.- The speed of rotation of the counter-shaft, and thereby of the main working shaft 1, is controlled by a dash-pot having a cylinder-2:3, stationarily mounted on the main frame-andhaving its'plunger carried by a cross bar 26, the ends of which are connected by links 27 with arms on the countershaft 2.

it will be seen that when the handle 7 is properly moved, both the countershaft and working shaft will be simultaneously and similarly actuated, power from the handle shaft being transmitted to the countershaft through the spring 15. If, however, the

. handle is moved forward abruptly and more rapidly than the dash-pot permits'the countershaft 2 to rotate, said spring will be stretched and the links 16, 17, will move with the arm 12 and handle shaft relative to the arm 11, on the countershaft, and the latter shaft and working shaft 1 connected therewith will only be moved with the proper speed.

Return movement of the handle is eftected by a spring link, connecting the uper end of the arm 12 on the-handle shaft with a fixed stud 28 on the main frame, and a spring 29 hav 'ing its ends connected respectively to the arm 12, below the handle shaft, and to the main frameor base of the machine. 11s shown'said spring link connecting the upper end of'the arm 12 with the main frame comprises two concentrically arranged springs 30, 31, the ends of which are connected to plates 32, 33,":cespectively engaging the arm 12 and the stud 28 see Fig. Each of said plates 32, 3-3 is provided with a reduced portion which extends into the inner smaller spring 31, and acts as a spreader therefor, the outer spring 30 being connected with ears 3+, on said The arm 12, being elastically connected at both ends with the main frame, is rapidly returned to itsnormal position after the handle has been depressed and released from the engaging means hereinafter refe od to without jar or strain on any of the s. "lfo insure a full movement of the handl Tin either direction a sector or plate 33 is mounted on the handle shaft and provided with. a serrated edge with which is adapted to engage a spring impelled dog 3-5 pivotally mounted on. the aforesaid bracket 10 attached to the main frame. To prevent the handle from being returned to its original position, before the working shaft has completed'its motion, means are provided for positively holding the handle in its forward, depressed, position, until the desired movement. of the working shaft is As shown, this means includes a toggle lever, the members 3-7, 38 of which are respectively pivotally connected to the arm 12 on the handle shaft and the frame plate 9 of the machine.

When the handle is moved downwardly into the position shown in Fi 4:, the toggle is adjusted so that its members 37, 38, form a continuous straight line from the point of its connection with the frame plate 9 to its attachment with the arm 12 and the handle is therefore locked in its depressed position until the member 38,0f such toggle detent raised or rocked about its pivotal connection with the -main frame. Such releasing of the toggle lock'is effected as the countershaft Q completes its movement by a spring impelled hammer 39 which is normally locked in a rearward position, with its actuating spring 4:0 under tension, by a hook or catch on a bell crank l1, the lower arm of which extends into the path of a stud or pin 42 on the arnrll of the countershaft. As the countershaft completes its movement, due to the forward swinging of the handle said stud or pin -12 engages the lower end of the bell crank 411, thereby raising the hook or catch thereon from engagement with the hammer 39 which is drawn suddenly forward by its'spring l0 and striking the rear face of a downwardly extending projection $3 on the arm of the aforesaid toggle lock, rocks said arm upwardly about its pivot and moves the pivotal connection ll oetw een the arms 37, 38 of the toggle above the line connecting the ends of said arms with the main frame and arm 12 on the handle shaft, thereby permitting the springs'connccting said arm 12 with the main frame to return the handle and parts controlled thereby to their normal positions. The arm 38 of the aforesaid toggle detent is provided with alaterally extending flange 45 which prevents said arm from being moved downwardly beyond the position which is effective for locking the handle, said flange hearing on the upper edge of the arm 37 of the toggle when the parts are in the position shown in Fig. 4. It will thus be seen that in'case the handle is moved forward more rapid than the shafts 1, are permitted to move, it will be locked by the toggle 37, 38 in its extreme forward position until thedesired movements of the shafts 1, have been completed, when it will be automatically released as above described. \Vhen the hair, dle is properly moved, that is, depressed with a speed corresponding to that with which the shaft 2 is permitted to turn. the toggle lock will be released at the time the handle reaches its forward position, and thereiore such lock will offer no hindrance to the return movement of the handle.

The hammer 39 is returned to its rearward position where it is engaged by the hook or catch on the bell crank 41 by a stud or pin 46, projecting laterally from. the bar center .16 of the f connection between the handle shaft arm 12 and countershaft arm 11, said p1n engaging in its rearward movement a projection 47 on the hammer.-

The stud or pin to which the rear plate of the spring 15 is connected and which stud or phi-extends through the slots 18. in the barsflit-1T, "18 not connected rigidlyv to the arm 11,

biit" e: -;teiids through suitable slots in the plate composing said arm and one end of each of two buffer springs 48 bears on a.

roller 49, mounted on said stud between the said toggle lock and is then released by the actionof the hammer 39, the'shock resulting from the sudden return movement of the handle is absorbed by the buffer springs 18, said springs being powerful enough to move the handle shaft to its normal position as the countershaft comes to rest.

As explainedin' the aforesaid patent No. 763,692, it is important and in fact essential that when eitherthe. subtotal key 5' or total key 6 is being depressed, the hantile '2' should be positivelylocked against 'aovemtent until the subtotal or total key has been fully depressed. It is equally important that neither of such sub-total or total keys should be depressed during a movementof the operating lever or handle.-

The' means for accomplishing these results will now be described. 51 designates a shaft which ismounte'd. in suitable bearings in the frame of the machine, and has an arm 52 connected, as described in the aforesaid patent, with thelever 53, whichis depressed when either the sub total key 5 or 5 total he 5 of the machine is operated. A second arm projecting from the shaft 51 in a irection opposite the arm 52, isconnected by a link with an arm 56 on one end of a shaft 57, on the other end of which shaft is,

secured acam-shaped vdetent 'Sa-id' detent is pi'o idedht its free end with a latcrally projecting flange lVhen either the sub-total key 5 or total key 6 is moved. through the connections just de scribed. the detent is rocked downwardly into the position shown in. dotted lines in Fig. (.3. During such'more'inent the flange in of such detent extends across the path of top tit) secured to the outer face of the bar to connet mg the arm lQnf the handle shaft with the arm 11 on the countershaft, and thereln' it positively pr ents the handle being nioved during the movementof the "s ulrtotal" key or total key. Normally the parts just described occupy the positions shown in Fig. :2, in which the detent 58 is held above tire stop 60 and offers no obstruc-' of a countershaft, connections .wherebyboth tion to the forward movement. of such stop. and handle connected therewith. If a. forward movement of the handle is commenced the stop (i0 is brought beneath the flange 59 of the detent 58 connected with the subtotal and total keys as shown in Fig. 4, and therefore it is impossible to depress either the total or sub-total keys during the time that the handle is being moved.
